tion occurs, the arms will be found to have become locked against opening movement.

Furthermore, it has been found, in actual practice, that because of slight variations in the mounting of the several brackets used to secure an awning to a building front, variations in diameter of castings, awning fittings and the like, it is practically always necessary, with present awning arms, to bend or distort the parts to insure proper folding operation. Where the arms are of finished stock or even are painted, it is impossible to accomplish this adjustment without marring the finish.

Therefore, with the general object in view of providing for an adjustable relation between the outer end of the outer arm and the awning pole or front board, the invention consists in certain novel and useful features of construction and organization of parts as hereinafter described and claimed; and in order that it may be fully understood, reference is to be had to the accompanying drawing, in which:-

Figure 1 is a top plan view of a lateral arm awning equipped with devices embodying the invention.

Figure 2 is an enlarged horizontal section taken through one of the devices or brackets, shown in Figure l as connecting the outer end of the outer arm to the awning pole or front board.

Figure 3 is an elevational view of the inner side of said bracket.

Figure 4 is an end view of the same.

In the said drawing, where like reference characters identify corresponding parts in all of the figures, the awning pole is shown as of tubular form, although it is to be understood that it may be a wooden pole or may be in the form of a front board, the parts being modified accordingly. For convenience of illustration, l is a wall bracket secured to the building front. Pivoted to the bracket l around a bolt I9, is the inner end of the inner arm 20. The outer arm 32 at its inner e d is provided with a fitting 55 wh ch is pivoted to a fitting 59 carried by the outer end of the inner arm 29. The outer end of the outer arm carries a suitable fitting 3! provided with a stop 36 for a purpose which will hereinafter appear, and the connection between said parts may be hidden or 5 protected by a sleeve 50, if the parts happen to be of tubular shape as illustrated. These parts are not otherwise detailed as they may be of any desired construction.

As stated in the objects of the invention, in 1.0 the modern type of lateral arm awning, compactness and neatness of folding isof prime importance and it has therefore been more and more necessary to insure that the lateral arms shall be pushed back into full folded position and 15 held against danger of becoming locked in such position as above mentioned. It has, therefore, been necessary to provide the front end of the outer arm with an offset or stop portion, such as shown at 36, which comes into contact with the front pole at the proper time and insures that further swinging movement of the pole with relation to the awning arm, shall not occur. Stopping relative movement of the outer arm with relation to the front pole or board, insures that further swinging or closing movement must take place around the intermediate and inner arm pivots. If this stop contact does not occur at the proper time, it frequently happens that the awning arm or the front pole is bent or distorted, or the parts may move to awning-locked position.

To provide a device which is of universal use with any type of awning pole or front ,board, the construction shown in the drawing or its equivalent may be employed. As shown, the device comprises a tubular clamp sleeve 18 to be fitted on the front pole 19 in accordance with whether it is to receive a right or left hand arm as shown in Figure 1. One wall of the clamp sleeve 18 may be split longitudinally from its opposite ends as at 80, the opposite portions of the sleeve being bent outwardly to form a pair of spaced ears 8| and a pair of larger spaced ears 82. The intermediate portion of the split side wall of the sleeve E8 is formed integrally with an unsplit cage or housing 83. Mounted in the cage for movement transversely of the axis of the sleeve, is a rack member 8A which is held in position against ro tation by a rib 84a, and is actuated back and forth by a bolt 85 in threaded relation therewith. The bolt 85 is held against longitudinal movement through engagement of its head 86 and a cotter pin 81 on opposite sides of the housing wall (see Figure 2).

The sleeve is transversely split as at 88 so that the clamp bolt 89 extending through the ears 8| may apply clamping pressure to hold the sleeve in position on the front pole 19. The opposite inner faces of the ears 82 are recessed to receive a pair of toothed disks 90, formed with a a pair of registering openings receiving the bolt or pivot pin 9| which passes through an opening in the ear 4| carried by the fitting 3| secured to the outer end of the outer arm.

The ends of the bolt 9| project through arcu-' ate slots 92 in the ears 82 so that by movement of the toothed disks 9B imparted by the rack member, the position of the pivot 9f may be adping and also to bind all ofthe parts against vibration. By eference to Figure 1, it will be evident that the cl'oser'the longitudinal axis of the pole to theaXis 0f the pivot bolt, the

- earlier the cb'ntac't ofth'e stop 36 with the front the position or; the center pivot connecting the After installation or an awning, the operator I adjusts the pivot bolts for the proper folding operation of each of the awning arms, it being apparent that an adjustment of fraction of an inch at this point is magnified by the length f the outer arm to effect a fairly wide swing or adjust I'rIent'in the position of the center pivot connect;

ing the we arms together. The exact time of contact of the stop with the front pole as regards a'r s, can only be determined by experiment with an; installation.

From the above description, it will be apparent that I have produced a construction embodying all of the features of advantage pointed out as desirable, and it is to be understood that while I have described and illustrated the preferred em bo'dimen't, I'reserve' the right to all changes withinthe spirit of-the' invention and without the ambit of the prior art.
